EDWARD 0. SMITH, OF LINCOLN, NEBRASKA.

BASE-BURNING STOVE.

SPECIFIOATIQN forming part of Letters Patent No. 234,340, dated November 9, 1880. Application filed April 19, 1880. (No model.)

To all whom it may concern:

Be it known that I, EDWARD 0. SMITH, of Lincoln, in the county of Lancaster and State of Nebraska, have invented a new and useful Improvement in Out-Offs for MagazineStoves, of which the following is a specification.

The object of my invention is to provide an improvement in the tunnels of base-burning stoves, whereby the coals can be retained in the tunnel in case a weak fire is desired or in case the fire has gone out and the ashes and cinders are to be removed, so that the coal in the tunnel can be dropped onto a fresh fire.

The invention consists in combining a plate having a handle and a cover-lifter having beveled ends with the tunnel of base burning stoves; also, in the peculiar construction of the plate-handle, as hereinafter described.

Figure l is a partial side and cross-sectional elevation of a stove provided with my improvement. Fig. 2 is a plan view of a stovelid lifter used to hold one of the forms of my improvement in place. Fig. 3 is a plan view of the slide provided with a handle. Fig. 4 is a cross-sectional elevation of a modification of my improvement as it is to be arranged in new stoves.

Similar letters of reference indicate corre sponding parts.

The self-feeding tunnel A of a base-burning stove, B, is provided with two clips, 0, projecting toward the center of the funnel at the lower edge, and the said clips support a plate, D, provided at the sides with shoulders E, which prevent the plate D from being pushed back too far.

The front of the plate D is provided with a recess, F, like that in an ordinary stove-cover for inserting a stove-cover litter, or with any other suitable device for attaching a handle to push the plate D, which is preferably made of castiron, forward or backward, as may be necessary. My improvement is to be arranged in this manner for new stoves, as their tunnels can be provided with the clips 0; but as I desire to apply my improvement to stoves already in use I have provided the plate D with a handle, G, which projects out of the stove and is braced and held by a stove-wrench or stovecover lifter, H, as shown in Fig.1. The sides of the plate D are preferably turned upward,

and the upper and lower sides of the handle G are toothed or serrated. The stove-cover lifter H is provided with two shanks, I I, at one end, and the cross-piece between these shanks is beveled, so as to form a sharp edge to rest against the identations of the upper side of the handle G. The tunnel may beprovided with a semicircular horizontal slot near the lower edge, and the sliding plate D may be passed through said slot, if desired.

The within-described improvement is used as follows: If the fire in the stove has gone out and the ashes are to be removed, it is desirable to retain the coals in the tunnel A, so as to use them at any time when a fresh fire has been kindled or it may be desirable to have a weak fire, and for this purpose it is necessary to decrease the pressure of the coal in the tunnel upon the fire below or to cut oif the supply of coal from the tunnel entirely. 1f the tunnel is provided with the clips 0 the end J of the stove-cover lifter H is passed into the recess F in the plate D, and the said plate is pushed along the lower opening of the tunnel in such a manner that it rests upon the clips 0 and until the shoulder E strikes the said clips. The cover-lifter His removed and the stove-door is closed. the coals in the tunnel and also prevents the production and escape of obnoxious and dangerous gases; but if the tunnel A is not pro vided with the clips 0 the plate D will have to be used, and is pushed along the under side of the tunnel A in a similar manner, theunder side of the handle G of said plate D resting on the lower rim, N, of the stove or on the lower edge, K, of the stove-door opening, the door M having been previously opened. The end J of the cover-lifter H is passed under the upper projecting rim, L, of the stove, and the lower beveled end of the cover-lifter is rested against one of the teeth on the upper side of the handle G, whereby the cover-lifter braces the handle G and counterbalances the effect of the weight of the coal in the tunnel. As the under side of the handle G is also provided with teeth, the same can be rigidly locked against the lower edge, K, of the stove-door opening independently of the distance it projects into the stove.
